How we approach roof lanterns in Eastbourne
Roof lanterns in Eastbourne means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the BN21 district and the rest of East Sussex, with a survey before any price is fixed.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
Neighbouring towns include Hailsham (11 km) and Seaford (13 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Eastbourne
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about roof lanterns in Eastbourne
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Can you work alongside my builder in Eastbourne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Eastbourne?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
